[Pgpool-committers] pgpool - pgpool-II: Fix SimpleQuery() to properly check extended query

[User T-ishii]

Log Message:
-----------
Fix SimpleQuery() to properly check extended query related commands.
Before it ignores them if query is not NULL. This is problematic if
frontend == NULL, which could happen with queries defined in
reset_query_list. The bug had been there since 2.1 BTW.
